ERSEN, a subject of the German Emperor,

and a resident of Hamburg, in the German Empire, haveinvented certainnew and useful Machines, of which the following is a specification. i

The present invention relates to improve- .rnents-in brick. molding and pressing machines, the object being to-provide a brickmaking machine in which the guiding and supporting disk for the movable pistons forming the bottoms of the molds in the mold-table is capable of being adjusted in height with relation to the intermittently-rotating moldtable. in orderto vary the height or depth, re-

- spectively, of the molds in which the said pistons work, so that bricks'or blocks of various thicknesses can be pressed by the same machine.

With this end in view my invention consists in certain novel features or construction and combinations of parts, as will be hereintion and plan, respectively, so much of my after fully described with reference to the accompanying sheet of drawings, inWhich- Figuresl and 2 represent in vertical-secimproved brick molding and pressing machine as is necessary to illustrate my invention'. I

Similar letters refer to similar parts throughout both views. a j

The mold table or disk a, containin'gthe molds a, (of which there may be any desired, number,) is mounted on a stationary vertical.

shaft 6 and arranged to rotate'intermittentl'y beneath a suitable feed hopper or casing c to 'bring each mold a in succession beneath the discharge-passage c in the bottom of the said feed-casing fromwhich the'clay or other ina-.

terial is forced or allowed to drop into the molds,

. Intermittent rotary motion may be imparted to the mold-table a a by means of a crank-.

arm d, mountedon a separate shaft e, the

crank-pin d of which engages'in radial slots or guides 03, formed in the periphery of the mold-table and arranged the same-angular distance apart from one another as the molds c; the arrangement being such that when the line, respectively. :By the-above transmitting means a smooth or gentle intermittent rotary motion is imparted to the mold-table,

The shaft in is suspended -1I1 suitable'bearings q of adjustable suspen- '1' 1-, screwed on external threads of the said suspension-rods. By means of the'adjustable suspension-rods the pressure exerted by the pressing-lever may be easily controlled. For absorbing shocks and the like a washer s of yielding material may be placed between the pressing-head '2' and the top plate 15, forming the bearing-surface for the nuts 1''.

For removing the compressed bricks out of themolds a suitable ejecting-lever u may be mounted .on a shaft n. This ejecting-lever u, carrying at its front. end asuitable pusher u, destined to act from below against the stem'of the pistons, maybe operated from the driving-shaft p in a similar manner as the pressing-lever 7;). The eccentric and eccentric-rod for actuatingthe ejecting-lever are, howcvermot especially shown in the drawings.

The operation of the brick-making machine is as follows: After the supporting-table g has been properly adjusted by means of the nuts I] h the shaft 6 is set in motion in order to intermittently rotate the mold-table a and to bring each mold a in succession beneath the discharge opening 0 ,of the hopper 0. Each mold as it comes into position to be charged with clay, rise, from the casing c has its piston f lowered. The filled mold on its further travel passes between the pressinghead and the pressing-lever, which latter is then rocked and caused to lift or raise the piston and to thereby compress the contents of the mold to form a brick or block of the required thickness. This position of parts is represented in Fig. 1. After the compression has been performed the pressin -lever rocks down, thereby allowing the freed piston to drop down and res-t again upon the supporting-table. The next movement or movements of partial rotation, as the arrange meiit may be, bring the mold containing the compressed or finished brick right over the ejecting-lever, which then by its rocking movement lifts the piston flush with the uppersurface of the mold-table, so. that the brickor block resting on the said piston may be readily taken off or removed therefrom. After the removal of the brick or block the ejectinglever rocking in opposite directionallows the piston to drop down again onto the supporting-table,whereupon themold-table continues its intermittent rotation.

2. In a brick-molding machine, the combination with a rotating table containing the molds and a head against which the bricks are pressed, of a supporting-table secured to combi u nation with a table containing the molds, of a supporting-table connected thereto, pistons and rotatable with the mold-table, pistons forming the bottoms of said molds andsupp'orted in: the supporting-table, means for adjusting the relation of said supporting-table to the 1nold-table,.mcans for intermittently.
